In March 1997, following several months of highly publicized controversy, the American Cancer Society (ACS) changed its recommendation for mammography screening of women ages 40-49 from once every 1-2 years to once a year. We examined the potential influence of this change on the mammography screening beliefs and behavior of 1,229 women, ages 40 -79, who obtained an “index” screening exam between October, 1996 and August, 1998. Respondents provided information on beliefs about the appropriate mammography screening interval for women their age, during a telephone interview, approximately one month after the “index” exam. A follow-up interview conducted, on average, 29 months later, collected information on subsequent screenings. Among 40-49 year olds interviewed through March, 1997, 48.5% endorsed annual screening; beginning in April, 1997 (the month after the guidelines change was announced), 65.2% endorsed this screening practice (p=.0012). This increased belief in annual screening among women 40-49 was sustained for the duration of the baseline data collection period (i.e., through August, 1998). No comparable increase in a belief in annual screening among women 50 and over was evident during the same time period. However, notwithstanding an increase in the belief in annual screening among 40-49 year old women, no concomitant increase in annual screening behavior for those interviewed after the guidelines change was observed over the subsequent 26 months. Although causal inferences must be made with caution, these data suggest that women’s beliefs about appropriate screening practices may be substantially influenced by recommendations conveyed through the lay press.
